TROLLEY-WIRE HANGER.

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed October 21, 1916. Serial No. 126,813.

To all whom it may concern:

Be it known that I, BERT A. WHITE, a citizen of the United States, residin at De- Michigan, have invented a certain new and useful Improvement in Trolley-Wire Hangers, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a trolley wire hanger shown in the accompanying drawings and more particularly pointed out in the following specification and claims.

One of the objects of this invention is to provide a device adapted to tilt sufficiently to relieve the hanger and line wire of the impact of the blow due to the transit of a trolley wheel beneath the hanger.

Another object of the invention is to provide against the accidental release of the wire clamping member from the insulated bolt carried by the supporting hanger ;-an objection common to devices having a screw threaded connection between the bolt and wire clamping member.

With the foregoing and other objects in view, the invention consists in the combination of parts and details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the device as herein disclosed, without departing from the spirit of my invention.

In the accompanying drawings which form a part of the specification.

Figure 1 is an elevation of the hanger showing in dotted lines the wire clamping member in its tilted position.

Fig. 2 is an elevation showing the oppo site side of the wire clamping member suspended from a fragment of the insulating bolt carried by the hanger.

Fig. 3 is a longitudinal central sectional view through the hanger and wire clamping member.

Fig. 4 is a side elevation of the hanger with the wire clamping member in cross section.

Fig. 5 is a perspective view of the insulated bolt carried by the hanger from which the clamping member is suspended.

Fig. 6 is an elevation of a pull-over hanger with parts in section, showing the trolley wire clamping member in cross section.

Referring now to the letters of reference placed upon the drawings.

A, denotes a hanger,-adapted to be supported by a cross Wire B, comprising a casting C, of bell-shaped form, open at the top to admit a bolt D, covered with a coating of suitable insulating material D The head D of the bolt D, rests upon an annular flange C within the hanger, its lower flattened end D projecting below the open bell-mouth of the casting.

E, is a trolley line clamp, having upwardly projecting ears E, spaced apart to receive the flattened end of the bolt D. F, indicates a transverse pivotal bolt projecting through the ears E, of the trolley line clamp and the flattened end D of the depending bolt D, and serves as a pivotal connection between these parts. The head of the bolt F, is cut away as indicated at F, and its cut away portlon bears against the flange E projecting from one of the ears,- the rib serving to keep the bolt from turning in its bearings. G, is a cotter-pin projecting through the end of the bolt F, to retain it in place. C is a closure cap having a screw-threaded connection with the top of the casting C. H, denotes the trolley wire secured to the clamp E, through clenching the side walls, 7, f, of the latter into impinging relation therewith. The shoulder at, above the flattened end of the bolt D, limits the tilting action of the clamping member E, upon the ears E, of latter contacting therewith. In Fig. 6 of the drawings is indicated one form of pull over hanger to be used in supporting the line wire at street or other corners where the trolley line is diver ed from its straight course. In place of the hanger indicated in the other views, a yokeshaped casting I, is provided with a downwardly projecting integral portion I, having a flattened end adapted to extend between the ears E, of the trolley line clamp E;-the parts being pivotally engaged by a transverse bolt F, secured by a cotter pin as previously described.

J, denote insulators pivotally connected with the casting I, by means of bolts J. K, indicate loops projecting from the outer end of the insulators to receive pull over wires,not shown.

Having indicated the several parts by reference letters the construction and operation of the invention will be readily understood.

The hanger is supported by cross wires B, in the usual manner ;the trolley line being held in the respective clamps by clenching their side walls around the wire. Upon the passage of a trolley wheel beneath the clamp the latter will tilt slightly, relieving the clamp and wire'of the strain occasioned through the passage of the trolley wheel thereof with a horizontal shoulder, a tiltable trolley wire clamp provided with an ear having a horizontal flange normally located in spaced relation to the shoulder of the supporting member and adapted to engage the same to limit the tilting movement of the clamp, and a pin piercing the flat- I tened end of the supporting member and the ear of the clampand having a cut away portion engagedwith the flange of the clamp whereby the pin is held against rotary movement in the ear of the clamp.

2. A trolley wire hanger comprising a tiltable trolley wire clamp, provided with spaced upwardly extending ears, one of the ears being provided at the top with a laterally extending horizontal flange, a pivot pin passing through the spaced ears and having a head with a straight peripheral edge arranged in engagement with the said flange to hold the pin against, rotary movement, and a supporting member having a flattened lower end arranged between the said ears and pierced by the said pin, said supporting member being also provided with a shoulder arranged to be engaged by the flange of the said ears to limit the pivotal movement of the clamp. v v

In testimony whereof, Isign this specification in the presence of two witnesses.
